Patented Dec. 15, 1931 UNITED STATES ALFRED ROSEWOOD, F SAN FRANCISCO, CALIFORNIA VALVE WrrH DETAGHABLE sPoUT Application filed September 19, 1928. Serial No. 306,932.

The invention relates to improvements in valves which are used on lawns and parks and concrete walks, or wherever it is ldesirable that the valve be substantially flush with the f surrounding surface. The usual construction Sli is an iron bei: having an outlet for connecting the hose and a square-headed screw holding a washer and a separate socket key for turning the water on and olf.

The above construction is not satisfactory because the worker is apt to destroy the Washer by turning the washer stem too severely, and the square head of the washer stem is often rendered useless by the use of pliers or pipe wrenches .vhich tend to round olf the corners.

The object of my improvement is to overcome the above mentiened dilliculties; to pro vide a valve of a relatively small circular form in which the valve seats automatically upon release of the valve opening means, and finally to dispense with separate socket keys and pipe Wrenches, and to provide a valve that may be operated only by means of a key which a part member of the `valve spout, and portable with the hose, and connected thereto.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred forms ef my invention are illustrated in the accompanying drawings, in

which:

Figure 1 shows a vertical section through the valve with a cap fastened thereto,

Figure 2 a vertical section through a spout, having means for operating the valve incorporated therein,

Figure 3 a plan view of the valve,

Figure 4 a side elevation of the combined Valve and spout with part of the casing broken away to show the interior,

a part being shown in section,

Figure 6 a vertical section through a modil fied form of valve,

Figure 7 a vertical section through a modilie'd form of spout, and

Figure 8 a plan View of the valve shown in Figure 6.

lVhle I have shown only the preferred form of the invention, I Wish to have it understood that.y v arious changes or vmodifications m`ay be Amade within' the scope of the claims hereto attached without departing from the spirit of the inzvention.` '55 Y Similar numerals refer to similar' parts throughoutthe several views; I prefer' to construct my invention inthe following manner. In the'form shown in Figures 1 to 5, a fitting j, is threaded ronthe'pipe 4 andv is provided with a hexagonal base' Gfrom which a dome-shape`dmemberw7 rises withl a flattenedl top perforated .las at 9, which constitutes the valve s eat 8. vTwo or'fmore' lugs 10 rise from the ytop of the dome and support a ,disc 11 which has a cylindrical housing'12 mounted thereon. A valve stem 13 is guided i by the disc and has the valve 28 threaded Vthereon belowthe valve seat. A spring 12 encircling the valve stem bears against the4 0 disc 11 and the head 13 of the valve stemfor normally seatingthe valve.vv The latter` is shown in detail in Figure 5, andr comprises a lug threaded on the stemV having a starshaped disc extending therefrom which/is covered on nboth sides with a layer of vulcanized rubber as shown at 7 and 7 lA cylindrical sleeve 14 is threaded to the base ofthedome and is formed, somewhat above the disc 11, with anfvinternal shoulder 15 and is threaded above the shoulder, as shown at 18, to receive the cap 19. The center of the latter is pivoted by means of a rivet 21 to a link 20, which latter'i's hinged to the v head of a Cotter pin V vwhich is s'lidably 85 received ina llug 22 extending from the sleeve The latter is yalso adapted to receive, upon removal of the cap, the spout 1 which may y be of any suitable-form and is preferably made inthe shape of aV goo'seneck. The Figure 5 a plan view of a valve washer,

spout may be let into 'the' upper end ofthe sleeve 14 and has, near'its lowerend, a shoulder 16 adapted to Seaton the shoulder lof the sleeve, while a threaded ring36 formed with handles 17 is engaged with the thread V18 in the sleeve for forcing the'shoulder 416 upon the shoulder `15. The spout is formed with a bearing 38 in axial alinement with the valve and has an operating pinv 'slidno able in the bearing which is normally urged outward by a spring 24. A pin 26 extending from the pin rides in an inclined slot 27 in the spout wall so that the pin may be advanced for bearing on the valve head and for opening the valve by a turning movement. The pin is operated by means of a knob 37 at the outer end thereof.

The device thus far described is intended principally to be used on lawns, where the fitting 5 may be -readily-.u-.nscrewed from the pipe for giving access to the valve in case the latter has to be renewed. 'When lmy invention is to be used in ,connection with cement floors or the like, where'the valve housing is embedded in the :cement and may not be removed, I preferto use the form illustrated vin Figures 6 to 8, vwhich gives access to the -v valve through the top ofthe housing 5 made of one pieceand provided with an internal Vshoulder 3l adapted to threadedlyA receive a -cage l1 havingja shoulder 32 limiting its ydownward fmovementand forming a valve :seat at .its bottom-for the valve 28 .which is lconstructed similarly to that shown in Fig v-fure 5. rIhecage has the cylindrical housing l2 Irising therefrom and serves 'as a guide n.for Vthevalve stem 13V while the valve head 13a is adapted to `reciprocate inthe housing 12" and .-is normally urged outward by the spring 12a. The lower-endof 4the housing l2 1 is made .hexagonal as .shown at 33 so that f it may be turned vby means of a socket ydo ence on the part vof the valve.

avrei-ich. The cap in this form is made freely removable v`andis provided with a groove Sli-into which a suitable wrench Amay be in- ,.'serted for turning the lcap. For this pur- .pose a person might use, for instance, the extreme eli-@1x35 of the special wrench shown in Figure 7, which is used for threading the ring .36 into the. valve housing.

The fspout shown in Figure T differs from thatvof Fig-ure y2 principally by the fact that vthe operating pin a for the valve is threaded into the spout housing as shown at 26pfor `imparting endwise movement to the ksame by .a turning motion. A v The operation -o-f kmy valve. will be readily understood from the foregoing description.

The lawn valve shown in Figures ly to V5 is normally cove-red by the capV 19 and does not appear above the surface of the lawn so that the latter maybe vmowed without interfer- 'Ihe spout as a rule Willgremain attached to therhose, and .an operator carries the hose with the spout from valve to valve, removing the cap and screwing on the collar V36. rIhe cap cannot be lost due to its hinged connection with the valve housing. After the connection has been made between the valve and the spout, the operator manipulates ythe pin 25 by turning thesame, which causes the vsmall pin 26 to ride in the slot 27 and to advance the main pin for opening the valve. vIt will be seen that a single spout in this manner may serve a large plurality of valves. As soon 'as the spout is removed or the pin 25 reversed, the valve is automatically closed by the spring 12 and also by the pressure within the water system. It will thus beseen that at no time can the operator exert undue pressure for bringing the valve washer to its seat, which in many cases is the cause for valve washers wearing out quickly. It will further be noted v`that ithe valve as shown in Figure l may easily be removed from the pipe l for givingfaccess Ato the washer in case a renewal should be required.

rIhe device shown in Figures 6 to 8 differs because it is intended for a different purpose. It is supposed to be embedded in concrete, which makes it desirable thatv the valve washer be accessible through the top of the valve, and in this form IA therefore fix the cage forming the valve seat in such a manner that the entire cage may be removed through the open top of the valve. I also show in Figure 7 an ordinary thread for advancing the pin 25a.

I claim:

l. In combination, a valve housing comprising a dome-shaped fitting adapted to be threaded on a water pipe and having' an opening in the top for forming a valve seat,` a valve adapted to seat thereagainst from the inside having a stem extending through the opening, a baiile plate supported above the fitting in spaced relation thereto, a cylinder rising from the baffle plate, a head on the valve stem slidable in said cylinder, spring means active on the head and tending to seat the valve, a sleeve surrounding the fitting and a spout adapted to be threaded on the sleeve having means therein for operating the valve.

2. In combination, a valve housing comprising a fitting adapted to be threaded on a water pipe and havingan opening for forming a valve seat, a valve adapted to seat thereagainst from the inside having av stem extending through the opening, means for guiding the stem having a baille associated therewith for defiecting the water laterally when leaving the valve opening, and a spout adapted'to be threaded to the sleeve and having means therein for opening the valve.

In testimony whereof, I have hereunto set
